The Gleacher Center of the University of Chicago houses the Graduate School of Business and also competes with nearby hotels as a conference center and banquet facility. The downtown location of the site allowed limited access and traffic congestion. In short, the project was to deliver a state-of-the-art, multi-use educational facility that would be built in a congested location and be completed within an 18-month deadline to accommodate the start of classes.
The interior of the structure was the first priority so workers could get up and down without lifts. The design called for two-hour fire-rated USG® Cavity Shaft Wall Systems in stairwells, elevator shafts and mechanical walls. Instead of using two layers of standard gypsum panel on the finished sides of the shafts, the project manager recommended using just one layer per side of 3/4-inch Sheetrock® Brand Gypsum Panels, Ultracode® Core, to achieve the same two-hour-rated system, saving valuable time as well as reducing labor and material costs.
USG also supplied gypsum panels and finishing, ceilings and wall systems. Using USG for all the materials not only ensured the proper fire-ratings but kept other aspects of the project simple so that the deadlines were met on time and within budget.
